CULTIVATOR.

SPECIFICATION forming part of Letters Patent No. 260,664, dated July 4,1882.

Application filed April 25, 1882. (No model.)

To all whom it may concern;

Be it known that we, WILLIAM L. 0oL'roN and HERSGHEL A. SOHERMERHORN, ofWaterman, in the county of De Kalb and State of Illinois, have inventedcertain new and useful Improvements in Cultivators; and we do herebydeclare that the following is a full, clear, and exact description ofthe invention, which will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, which. form a part-of this specification, and inwhich- Figure 1 is a perspective view of so much of the frame andoperative parts of a ridingcultivator as is necessary to illustrate ourinvention. same; and Fig. 3 is a sectional detail view, on an enlargedscale, of the coupling which connects the arch to the adjustableshovel-beams.

Similar letters of reference indicate corresponding parts in all thefigures.

Our invention has relation to so-called riding or sulky cultivators; andit consists in the means or mechanism for adjusting the position of theshovel-beamsin relation to the line of draft, substantially ashereinafter more fully described and claimed.

To avoid obscurity and unnecessary prolixity in the description of ourimprovement, we have shown and shall describe only so much of acultivator as is necessary to a proper understanding of the nature andoperation of the operative parts which constitute our improvement.

A is the tongue, which consists of two bars, a at, having thedouble-tree A attached to their converging front ends. At theirdiverging rear ends the tongue-bars a a form loops or eyes, by whichthey are attached to the axle B. The latter is bent at both ends to formelbows b 1), upon which the wheels 0 G are journaled.

D is a cross-bar, which is fastened transversely across tongue A,parallel to the axle B, by clips, bolts, or other suitable means, atboth ends of which are hangers D D, adapted to turn upon pivot-bolts dd, by which they are fastened to cross-bar D. In the lower ends of thesehangers are hinged the parallel beams E E, at the rear ends of which areboxes 6 e for connecting them with the dragbars or shovel-beams F F,which carry the shovel-standards and plows or shovels H. The ends of thebeams E and F, which are in- Fig. 2 is a plan or top view of the gles ofthe parallel beams E may be changed or adjusted without affecting theposition of the axle. 7

The shovel-beams F F are connected, back of the coupling-boxes e c, byan arch, G, the bent ends of which are inserted through couplings H,each of which ishinged between ears hh on the top of beams F, and heldin said couplings adj ustablyand detachably byset-screw t. Thisset-screw may be inserted through the top of coupling H, so as to bear.with its lower end against its appropriate end or arm of arch G or itmay be inserted through an auxiliary box, t", working in a recess incoupling H, through which the end of the arch is inserted, as shown inthe sectional detail view, Fig. 3. By this construction and combinationof the parts F F, G, B, E E, D D, D, and A the angle of the drag-bars orshovel-beams F F may be changed relative to the line of draft,asrepresented by the tongue A and axle B, without changing the angle ofthe shovels, which will always present a true face to the ground. Inother words, the drag-bars will remain parallel to the line of draftirrespective of their adjustment to one side or to the other thereof. 7

We claim and desire to secure by Letters Patent of the United States- Ina cultivator, the combination of the tongue A, having cross-bar D,provided with the swiveled hangers D D, axle B, having swiveled orpivoted boxes I I, jointed parallel dragbars E F and E F, connectedrespectively by the boxes 0, and having couplings H H, provided with theset-screw t, and transverse connecting-arch G, substantially as shownand described, for the purpose set forth.

In testimony that we claim the foregoing as our own we have hereuntoaflrixed our signatures in presence of two witnesses.
